Frequently Asked Questions
What is the input voltage range of the REF3325AIDCKRG4?
The REF3325AIDCKRG4 accepts input supply voltages from 2.7V to 5.5V, making it compatible with both 3.3V and 5V powered systems. This input range ensures the device can provide its regulated 2.5V output from common microcontroller and system supply rails without requiring additional voltage conversion.
What is the output accuracy and drift of the REF3325AIDCKRG4?
The REF3325AIDCKRG4 provides 2.5V nominal output with ±0.15% initial accuracy (2.49625V to 2.50375V) and a maximum temperature coefficient of 30 ppm/°C. This combination of initial accuracy and low drift makes it suitable for 12-bit ADC and DAC reference applications in industrial measurement systems requiring stable performance over the -40°C to 125°C operating temperature range.
How does the REF3325AIDCKRG4 differ from the REF3325AIDCKTG4?
The REF3325AIDCKRG4 and REF3325AIDCKTG4 are functionally identical, both providing the same 2.5V output, 30 ppm/°C drift, and 3.9µA quiescent current. The primary difference is packaging format: the R suffix indicates tape-and-reel packaging for automated SMT assembly lines, while the T suffix typically indicates an alternative packaging format. Designers select based on their production assembly method.
What applications are best suited for the REF3325AIDCKRG4?
The REF3325AIDCKRG4 is best suited for precision ADC and DAC voltage references, data acquisition front ends, sensor signal conditioning circuits, and laboratory measurement instruments requiring a stable 2.5V reference. Its ultra-low quiescent current of 3.9µA also makes it ideal for battery-powered portable devices including handheld meters, GPS devices, and remote wireless sensor nodes where power efficiency is critical.
